This invention relates to improvements in an.

highly'complicated mechanism which would be.

apt to get out of` working order; to provide an automatic phonograph which is of compact conf struction -so that it will fit into a comparatively small cabinet or casing, and, in general, it is .the object of the invention to provide an improved automatic phonograph of the type re- ,n ferred to. f

Other objects and advantages of the invention will be understood byv reference to the following speciiication and accompanying drawings (six sheets), in which an automatic phonograph embodying a selected form of the invention is illustrated.

In the drawings:

Figure 1 is a plan. g Figure 2 is an end elevation of the left-hand end of Figure l.

Figure 3 is 'a section on the line 3--3 of Figure 1.

Figure 4 is a 'section similar to Figure 3, but

showing certain` parts of the mechanism in a 35 changed position.

Figure 5 is a section von the line 5--5 of Figure 3.

1 Figure 6 is a section onthe line 6-6 ure 3.

Figure 7 is an illustratipn of a certain detail of construction.

Referring now to the drawings, my improved phonograph mechanism is mounted in a frame of generally rectangular portions. The frame includes a base frame II) of cast metal or other suitable construction, as clearly shown in Figure 3, and suitable uprights, such as indicated at II, which support top frame memberssuch .as shown at I2, I2?,- I2b and I2. The top frame ggf, member I2 is a substantially square frame element, as clearly shown in Figure 1.

The phonograph playing mechanism includes a turntable I3 mounted on the upper end of a spindle I4, the spindle I4 having a bearing near its upper end in a longitudinally extending frame of Figelement I5, as indicated at IG, and a bearing at its lower end, as indicated at I1, the lower bearing constituting' a part of the lower or base frame I0. The spindle I4 is suitably supported against downward sliding movement at its lower end in the bearing Il, and it is adapted to be rotated by means of an electric motor I 8 which is provided" with a motor shaft I9 geared to the spindle I4 by means of gears 2D and 2l which are secured to the shafts I9 and I4, respectively. Suitable coin-controlled mechanism, herein designated C, including an electric switch 22, may be provided for controlling an electric circuit to the motor-IB or an ordinary manually controlled electric switch may be provided if the coin-control element is not desired. The ar.- rangement is such that the motor I8', and thereby the turntable I3, is continuously driven during all operations of the mechanism which will presently be described. The coin-control mechanism may be of any suitable type, and inasmuch as no invention is claimed in the specific type of coin-control mechanism, no detail description thereof will be given in this application. For co-operating with a record on the tumtable I3, an electric pick-up 23 is provided, the pick-up having suitable means indicated at 24 for holding a needle or Stylus 25. The pick-up 23 includes or is supported by a supporting arm 26 which is provided, as indicated at 21, for vertical swinging movement about a horizontal axis and, as indicated at 28, for horizontal swing- .fing movementl about a vertical axis. 'Ihe horizontal pivot axis is formed by, means of a horizontally extending pivot pin which extends through an end portion 29 of thesupporting arm 26 and a head portion 30 of the vertical pivot pin 3I which is journaled in a bearing 32 which depends from the top frame member |28. (See FigureV 2.) The pick-up member 23 is secured 40 to the free end of .the supporting arm 26 by means of an arm or bracket 33 which-is rigidly secured at yone end to the pick-up member 23 and pivoted, as indicated at 34, to the free end of the supporting arm 26. The bracket 33 extends beyond the pivot 34 and has itsY free end provided with a depending pin 35 which ts in a slot 36 in the adjacent end of an arm or lever 31 which is pivoted intermediate its ends, as indicated at 38, to the supporting arm 26. The other end of the lever 31 is slotted, as indicated at 39, and straddles a pin 49 which extends upwardly from, and is held in, xed position by the top frame member I 2*. (See Figures l'and 3.)

The lever arrangement, just described, for

mounting the pick-up device 23 is such that the pick-up member 23 is maintained in substantially xed, predetermined relation to a radius of the -record in all positions of its travel across the face of the record. The main purpose of this arrangement is to facilitate the use of so-called permanent needles or styluses which, in their present `commercial form, embody a chisel-like point which must not be turned at an angle -in the sound groove of a record which it engages. The above-describedI arrangement'is such that the pick-up device and the chisel-shaped needle end are maintainedA substantially tangent to the engaged record groove in all positions of the pick-up device. By reference. to Figure 1, it will be seen that when the pick-up device 23 starts to travel inwardly across the face of a record on the turntable I3, it will travel in an arc about the vertical pivot axis 28 of the supporting arm 26, and that the lever 31 will be caused to swing on its intermediate pivot 38 by reason of its engagement at one end with the xed pin 40, the result being that the, opposite end of the lever 31 tends to swing the pickup member 23 about the pivot 34 in a direction reverse to the direction of travel across the face of the record.

When the playing of a record is completed, the pick-up device 23 is automatically elevated so as to remove the stylus 25 from the record groove and it is thereupon returned to its initial or starting. position, as illustrated in Figure 1. For accomplishing this, a spider 4| is provided, this spider being secured to the upper end of a rod or bar 42 which is mounted for vertical sliding movement in bearing openings such as indicated at 43 and 44 in the top frame member I2a and base frame member I0, respectively. The spider 4| includes a forwardly projecting arm portion 4| which carries a pin 45, and it includes a laterally extending arm 46 which extends under the pick-up supporting arm 26, as clearly shown in Figures 1 and 3. The outer or free end of the laterally extending arm 46 is provided with a downwardly extending pin 41 which is slidable in a suitable opening in an ear 48 constituting a part of the top frame member I2.

Vertical movement o'f the rod or bar 42 is effected by means of a cam 49 which is carried by a cam shaft 50, the latter being mounted for rotation in suitable bearings carried by upstanding base frame parts 5| and 52, as clearly shown in Figures 2 and 3. The cam 49 actuates the rod 42 through the agency of a lever 53 which is pivoted intermediate its ends, as indicated at 54, on a lug 55 extending upwardly from the `base frame I0. One end 56 of the lever 53 engages the peripheral cam surface 49, while the other end 51 of the lever engages a cross pin' 58 carried by the rod 42. It willI be seen that when the cam 49 depresses the end 56 of the lever, that the end 51 will be swung upwardly, and that through its engagement with the pin 58 the rod 42 will be elevated. When the rod is thus elevated, the centering pin 55 will be withdrawn from the record, as indicated in Figure 3, and the arm 46, engaging an ear 59 which depends from the arm I8 of the pick-up mechanism will elevate the pick-up by swinging the same upwardly about the horizontal pivot 21.'

As an incident to such elevation of the pickup device, it is swung from its innermost position to its outer or starting position. The means for effecting such return movement llClllde 31.1 am! depending record-centering 60 which is secured to the lower end of the pivot pin 3|, and a bell crank 6| one arm 62 of which is connected by means of a link 63 to the arm 60. The connection between the link 63 and arm 60 is. preferably an adjustable connection formed by providing the arm 6 0 with a tapped, apertured ear adapted to receive the screw-threaded end of the link, as clearly illustrated. The other arm 64 of the bell crank 6| extends into the path of a pin 65 which is carried by the rod 42.' The bell crank 6| is pivoted in a depending lug or ear portion '86 which depends from the top frame meinber l2, It will be seen that when the bell crank is rocked counter-clockwise (see Figure 2) by reason of the upward movement of the rod 42 and engagement of its pin 65 with the bell crank arm 64, the lever 60 will be swung counter-'clockwise (in Figure 5) so that the supporting arm 26 and pick-up member 23 are correspondingly moved to outer or starting position. The laterally extending arm 46 of the spider 4| is provided with a stop shoulder 61 and with a notch 68 for co-operating with the ear 59 to position the pickup with its stylus immediately above the outer groove of a record placed on the turntable.

Upon downward movement of the rod 42 and parts carried thereby, it will be seen that the pickup 23 will be gently lowered until its stylus engages the record; In the event that the first sound groove of the record is spaced inwardly from the point at which the stylus engages the record, a spring 69 serves to initially swing the pick-up device inwardly until the sound groove is engaged. It will, of course, be understood that the spider 4| is lowered a suiicient distance after the stylus engages the record to cause the ear 59 to leave the groove or notch 68 so that the pick-up may freely follow the sound grooves of the record and travel crosswise thereof.

The cam shaft 58 and the various cams thereon are actuated automatically upon completion of the playing of a record. 'I'he mechanism for actuating the cam shaft will now be described.

For transmitting power to the cam shaft 50, the shaft is provided with a worm wheel 10 which meshes with a worm gear 1| rotatably mounted on the spindle 4. 'Ihe upper end of the worm gear 1| is provided with a clutch notch 12 (see Figures 3 and 4) adapted to receive a clutch lug 13 of a clutch element 14 which is slidably mounted on the spindle |4. ber 14, while slidably mounted, is held against rotation relative to the spindle by means of a pin 15 carried by the spindle and projecting into a notch 16 provided in the clutch member. 'I'he clutch membery 14 is adapted t o gravitate into engagement with the clutch end of the worm gear 1| when permitted to do so. For controlling such sliding' movement of the clutch member 14, a lever or arm 11 is provided, the arm 11 being pivoted at its outer end, as indicated at 18, to the vertically adjustable rod 42, andprovided at its inner end with forked arms 13 which straddle the clutch member 14 and lit into an annular groove 80.

A fulcrum for the lever 11 intermediate its ends is provided by means of a depending hook member 8| which is pivoted at its upper end, as indicated at 82, to a lug 83 depending from the top frame member I5. The hook 8| is adapted to swing transversely of the length of the lever 11 and near its lower end is recessed inone edge to provide a fulcrum` seat 84 which is adapted to receive the bottom edge of `the lever 11. The

The clutch memhook member 8| is connected by means of a link 25 being played. Disk records such as 85 to the lower end of the depending arm 86 of a bell crank lever which is pivoted, as indicated at 81, on a lug portion 88aL of the frame member l5. The other arm 88 of the bell crank lever extends substantially horizontally and is'serrated on its top edge, as indicated at 89. A spring 90,-extending between an ear 9| of the bell crank lever and a pin 92 carried by the lug element 88, serves to normally swing the bell crank lever 86-88 until the arm 86 engages a stoppin 93 which is carried by the said lug 88a. The b'ell crank arm 86 is provided with a forwardly extending ear 94 which is adapted to be engaged by an adjustable screw 95 carried by the lower end of a depending lug 96 formed integral with the arm 60.

i During the playing o a record, the clutch member 14 is held disengaged from the clutch end of the worm gear 1| by means of the lever 11 which rests intermediate its ends on the fulcrum seat 84, the outer end of the lever being held in down position with the rod 42, it being understood that the latter is in -down position when a record is are played on the phonograph mechanism herein involved are ordinarily provided with an innermost groove, the diameter of which is approximately uniform for all records. If the actual sound groove terminates before the innermost groove is reached, a

` justable screw 95 its pivot 18, with quick spiral groove is provided for conveying the pick-up device from the actual sound groove tothe innermost groove just referred'to. The adis so adjusted that when the pick-up device travels over a quick spiral groove such as referred to, the screw will engage the ear 94 and thereby swing the depending arm 86 about its pivot 81. Such swinging movement is transmitted through the'llnk 85 to the hook lever which is accordingly swung Figure 2), with the result that the fulcrum seat 84 is removed from under the lever 11, thereby permitting the lever' to swing downwardly about the result that'the clutch member 14 engages the clutch end of the worm gear 1 Thereupon, the cam shaft 50 and cam 49 are rotated, with the result that the lever 53 is actuated to elevate the 'rod 42 to accomplish the .device 23 travels over functions previously explained.

The bell crank arm 88 with its serrated top edge 89 is provided for co-operating with a dog 91 which is pivoted at 98 in the free end of the arm 60 (see Figures 2 and 5). When the pick-up the face of a record the dog '91 .rides over the serrated top edge of the bell crank arm 88, necessarily assuming a position at an angle to the vertical, the angle being approxi- It will be observed that if it the playing of a record, it is mately 45 degrees. is desired `to stop only necessary to manually lift the pick-up device and supporting arm 26 and to swing the same towards its starting that the dog 91 will force` thebell crank arm 88 downwardly, thereby swinging the bell crank arm v 86 to the right-to`- effect the engagement of the clutch elements 14"and 1| and operation of. the cam shaft 50, as previously described.

A record magazine associated with the playing mechanism previously described, lcomprises a frame element |09 which is in the form of a rectangular loop. The frame loop |00 is vertically, slidably mounted on rods |0||0| at opposite 'sides o'f the frame by means of ears |02 which extend laterally from the opposite ends of the frame |00 and by` means of ears |03|03 which extend laterally from the lower ends of downwardly extending lugs |04. It will be under- (to the right in' position, 'the result being I stood that the ears |02 and |03 are apertured to slidably t the rods |0|. Mounted within the looped frame |00 is a shelf structure embodying a plurality of vertically spaced shelves |05, each of w ich serves as a support for a record R.

e magazine structure just described is supported by means of a lever |06 which is pivoted intermediate its ends, as indicated at |01, and lug |08 which extends upwardly from the base frame. The rearward portion of the lever |06 is provided with an anti-friction roller |09 which engages the edge of a cammember ||,0 which is rotatably mounted on a shaft the latter being rotatably supported in upwardly extending posts ||2| |2, as clearly shown in Figure 6. The front end of the arm |06 is provided i screw-threaded and fitting a correspondingly tapped aperture in a pin ||1 which is rotatably' mounted in the post H5. It will be observed that the threaded connection between the link ||4 and pin or stud ||1 provides for' adjustment of the magazine relative to the ylever |06. For

cornterbalancing the weight of thesmagazine and records carried thereby, the forward end of the lever |06 is connected by means of a spring I0 to a stationary portion I9 of the base frame.

It will be evident that the cam ||0 is opera-l tive to control the position of the magazine |00. For automatically rotating the cam ||0 step by step, the following mechanism, is provided:- A ratchet wheel |20 is rigidly secured to the cam ||0 so as to be rotatable therewith and a pawl |2| is associated with the ratchet for moving the same. The free end of the lpawl |2| is provided with a laterally extending portion` |22 whichis adapted to engage behind the respective teeth of the ratchet wheel, and the other end of the pawl is pivoted to the upper end of lug projecting upwardly from the base frame I0.

The lever |26 is also provided with an antifriction roller |28 which engages the periphery of a cam disk |29 which is carried by the cam shaft 50. It will be seen that when the cam shaft 50 rotates, the cam |29 will act on the lever |26 to force the link.|25 to move rearwardly, thereby swinging the lever |23 and pawl |2| rearwardly. The pawl |2| is accordingly operative to turn the ratchet wheel |20 the distance of one tooth of the ratchet. The cam ||0 is so shaped that the extent of rotation imparted to it is suilicent to raise the lever |06 and magazine a distance equal to the spacing of the rec ords R in the magazine. For restoring the pawl |2| to operative position relative to another tooth of the ratchet4 |20, the cam |29 is provided with a co-operating ledge portion |30 which, with the periphery |29 of the cam, forms a groove |3| which receives the cam roller |28 and serves to positively swing the lever |26 4counterclockwise, as viewed in Figure 3.

v the inclined cam edge as indicated at |42 to For disabling the pawl |2| to cause repeating of a record, I have provided a cam device for adjusting the pawl |2| to inoperative position. 'I'his device includes a plate member |32 which is mounted on the shaft but not secured thereto. The outer face of the plate |32 engages al friction disk |33 which is carried by a collar |34 secured to the shaft compressed between the other face of the plate |32 and the adjacent face of the ratchet wheel |20 serves to maintain the plate |32 in frictional engagement with the friction disk |33. The shaft is provided at its free end with a knob |36 for facilitating manual turning of the shaft. By manually turning the shaft counter-clockwise as viewed in Figure 3, the pawl |2| will be elevated out of engagement with the ratchet by means of a cam edge |31 (see Figures 3 and 7) which acts against a projection |38 formedintegral with the ratchet-engaging portion |22 of the pawl. (See Figure 6.) When the projecting portion |38 of the pawl is disposed at the high point |39 of the cam edge |31, the pawl will ride idly over the ratchet teeth. Of course, it will be understood that upon such movement of the pawl, the plate |32 is swung about the axis of the shaft Upon return movement of the pawl, the projection |38 thereof Will ride down |31 inasmuch as the plate is frictionally held against movement, the frictional holding power being greater than the small amount of friction between the pawl proiection |38 and cam edge |31. When the projection |38 engages the leg |40 at the front end of the cam edge |31, it will, of course, positively force the cam plate |32 to move forwardly. As an incident to such movement, the pawl portion |22 will ride upwardly over the back side of one ofthe ratchet teeth, this being permitted by reason of the depth of the opening over the cam edge |31. As soon as the pawl portion |22 passes over thev teeth on its return movement, it will drop down behind the tooth to be in position to engage the same for effecting the necessary adjustment of the` record magazine.

A locking pawl |4|, pivoted at its lower end a lug formed integral with the base frame |0, is provided for locking the ratchet |20 against rearward rotation. The upper end of the pawl |4| has a laterally extending portion |43 adapted to engage back of each ratchet tooth, ai spring |44 serving to yieldably hold the pawl in such position. The lever |23 is provided near its upper end with a projecting lug |45 which is adapted to enter one of the notches |46 formed in the rear edge of the depending post ||5. This locking lug |45 serves to prevent adjustment of the record magazine when the parts are ln playing position, as illustrated in Figure 4. A pointer |41, secured to one ear |02 of the frame |00, operates with an index chart |48 mounted in xed position on the supporting framework, this chart being indexed to indicate the selections available in the record magazine. Whenthe phonograph is at rest, i. e.`, the parts are in non-playing position, and all of the records are inthe magazine, the magazine may be adjusted manually to provide foithe playing of any selected record. This is accomplish :d by turning the knob |36 and shaft clockwise, as viewed in Figure 3. The ratchet wheel |20 and the cam ||6 are caused to turn under these conditions by means of a ratchet member |49 which is axially, slidably, but non-rotatably mounted on the shaft and adapted to engage a corresponding ratchcated at |66, to the lever |64.

et formation |50 on the cam disk ||0. A spring |5| compressed between a, lug |52 extending upwardly from the base frame 0 and the'adjaceni end of the hub of the ratchet |49 serves to yieldingly urge the ratchet |49 into engagement with the ratchet |50. It is important to prevent manual adjustment ofthe record magazine during such time as a record is disposed on the turntable or in the process of being transferred from the magazine to the turntable, or vice versa. 'Ihis is accomplished by means of a cam ear |53 struck out of the thrust bar |25 for engaging a flange |54 formed integral with the hub of the clutch |49. When the parts are in playing position, as shown in Figure 4, the cam ear |53 is operative to hold the ratchet member |49 out of engagement with the ratchet- |50 so that manual turning of the shaft will be inoperative to adjust the magazine.

The records are transferred from the magazine to the turntable and returned from the turntable to the magazine mainly by means of a pair of co-operating rollers |55 and |56 which extend between opposite frame members and are rotatably mounted therein. The upper roller 55 is mounted in an elongated slot"| 51 which permits the upper roller to be separated from the lower roller |56. The lower roller |56 is driven by means of a friction wheel |58 which alternately engages the bottom of the turntable I3 and the top of a driving disk |59 which is carried by the spindle |4. The driving wheel |58 is operably connected tothe roller |56 by means of a chain |60 which extends around suitable sprockets carried by the shaft of the Wheel |58 and the shaft of the roller |56. The record is fed into the bite of the rollers |55 and |56 from the magazine by means of a lever |6| which is pivoted at its lower end, as indicated at |62, on a lug formed integral with the base frame I0. The upper end of thelever |6| is provided with a projection or ear |63 which is designed, upon swinging movement of the lever 6| to engage the adjacent edge portion of a record in the magazine to thereby displace the same towards and into the bite of the said rollers |55 and |56. A record is fed from the turntable I3 to the magazine by means of a lever |64 which is similar to the lever |6| just described. The levers |6| and |64 are connected for simultaneous operation by means of a connecting link or bar |65 which is pivoted, as indiand at |61 to the lever |6|. The connecting bar |65 carries an anti-friction roller |68 which co-operates with a segmental cam |69. The connecting bar |65 and the levers |6| and |64 are normally swung to the position indicated in Figure 3 by means of a coil spring |69 which is connected between an upstandlng bracket member |10 carried by the bar |65 and a suitably spaced point of the thrust bar |25. Movement under the influence of the spring |69B is limited by means of a stop pin |1| carried by the frame member |2=.

As previously stated, the driving wheel |58 is adapted to alternately engage lthe turntable |3 and the driving disk |59. For controlling engagement of the driving'wheel |53, the bracket member |10 of the bar |65 is provided with a pin |12 which co-operates with yielding fingers |13 and |14 which depend from the hub portion |15 of the arm |16 in which the driving wheel 58 is rotatably mounted. The arm |16 is pivoted for rocking movement, as indicated at |11, in a lug depending from the frame l5.

The operation of the mechanism may be brieily Cil `mitted to the wheel shaft and the pick-up device 23 moved to its outermost position, the first operation will be that of displacing a record (in this instance, the record indicated at RX) from its normal position in the magazine into the bite of the rollers |55 and |56. This is accomplished when the roller |68 of the bar |65 is engaged by the front end portion |18 of the cam |69 and the bar |65 is caused to move to the left in Figure 3. The projecting portion |63 of the lever |6| is thus caused to engage the adjacent edge of the record'RX to slide the same into the bite of the rollers |55 and |56.

When the bar |65 movedto the left, the pin |12 engaged the yielding member |13 to .swing the driving wheel arm |16 upwardly about its pivot to bring the driving wheel |58 into contact with the bottom side of the turntable |3. The turntable is continuously rotated by the electric motor so that rotation of the turntable is trans- |58 and from the wheel |58 by means of the chain |66 to the lower roller |56. Ihe direction of rotation of the turntable is such that the roller |56 is then rotated in a counterclockwise direction, as viewed in Figure 3, whereby the roller', in co-operation with the upper roller |55, serves to transfer the record to the turntable. Thel rollers |55 and |56 rotate with suiiicient rapidity to impart sufficient momentum to the disk to throw the disk clear of the rollers to a position in which the usual axial opening of lthe record may be enteredy by the centering pin 45. Upon completion of the record-transferring operation of the rollers |55 and |56, the roller |68 of the bar |65 drops to the recessed end portion |19 of the cam |69.which, permits the spring |69a to move the bar |65 to the right suiiciently to cause the driving wheel |58 to assume a neutral position, i. e., out of driving engagement with both the turntable and the driving disk |59. Atabout the same time that the roller |68 engages the recessed cam portion |19, or slightly prior thereto, the cam-engaging end 56 ofthe lever 53 rides down an inclined portion |80 of the cam 49 and enters the notch indicatedvat |82, thereby permitting the outer end 51 of the lever 53 to swing downwardly under the weight of the rod 42 and parts supported thereby. When the rod 42 is thus lowered, the centering-pin 45 enters the central aperture of' the record and the pick-up'device 23 is lowered into engagement with the starting end of the record sound groove.v Inasmuch as the fulcrum lever 8| is disposed in its operative position, as shown in Figure 2, lowering movement of the rod 42` will cause the lever 11 to seat on the fulcrum ledge 84, the parts being so arranged that suchseating isveifected before the rod 42 ihas reached its lowermost position. During the final portion of the downward movement of the rod 42, the lever 11 is caused to swing about the fulcrum seat 84, with the result that the clutch member 14 is moved upwardly and disengaged from the clutch end of the worm gear 1|. The playing of the record is then effected, and when the stylus reaches the innermost groove of the" record, the adjusting screw 95 engages the tripping arm 86 to disenga'ge the fulcrum lever 8| from the lever 11 with the result that the cam 58 is again set in rotation. The next succeeding operation to take place is that of elevating the pick-up device and record-centering pin.

f member |29. It will be seen "claims:V the same tion of a record-storage This is accomplished throughthe agency of the cam 49 which operates onthe lever 53 in the manner previously explained. After a small amount of turningmovement of the cam shaft 50 and the cams carried thereon, `the roller v|68 of the connecting bar"|65 is freed from the recessed cam portion |19 whereby the spring |69'l is permitted to move the bar |65 to the right in Figure 4. The lever |64 is thereby caused to engage the record von the turntable to feed the same into the bite of the transfer rollers |55 and |56. Rotation of the rollers |55 and |56 is then eifected in the proper directionto feed the record to the magazine by reason of the fact that in its movement to the right, the pin |12 engaged the yielding member |14 to thereby swing the driving wheel arm |16 downwardly about its pivot to bring the driving wheel |58 into engagement with the'driving disk,|59. Such engagement between the driving wheel |58 and driving ,disk |59 is, of course, operative to rotate the wheel |58 in a clockwise direction, the roller |56 being then similarly rotated.

As soon as the record is delivered from the turntable to the magazine, the cam |29 is operative to swing the lever |26 to the right in Figure 4, with the result that the pawl |2| acts on the ratchet wheel |28 to turn the cam a distance sufiicient to raise the lever |06 sufficiently to align the next lower record in the magazine `will be that of transferring a record' from the magazine to described.

The coin-control mechanism indicated at C in Figure 5 may be of any suitable type. In this instance, 'I have illustrated it as being controlled by means of a short pawl |83 which is designed to be engaged by a pin |84 carried by the cam that each cycle of operation of the mechanism involves one complete revolution of the cam shaft 5|), wherefore the pin |84 will engage the coin-control operating lever |83 once for each record played.

' The described and illustrated mechanism, as compared with other automatic` phonograph mechanisms of similar types,l is comparatively simple and free from complicated devices which the turntable in the manner above require a. high degree of accuracy ln manufactm'e as well as in the extent of movement imparted to the respective parts. Because of its simplicity, the structure may be manufactured at an unusually low cost and its operation is highly satisfactory and free from the requirement of frequent adjusting;
